WATER-HEATER.

i Specifica tion of Letters Patent.

Application tiled May 1, 1909.

Patented May 3, 1910.

Serial No. 493.294. Y

To all whom it may concern:

Be it known that I, Howann NADIA" Mooor, a citizen ot the United States,re-

siding at )Tew Orleans, in the parish ot" Orleans and State otLouisiana, have invented certain new and useful Improvements inl.\"'aterslleatersa ot which the followingr is a specification. y

The obJect of-my invention 1s to provide a water heater of simpleconstruction, of

compact and convenient size and shape, and economical and eftective 1nproviding for the exposure of a larger superficial area of vater to theheating surfaces.

In the accompanying drawings; Figure l is a side View of a longitudinalsection through the heater. Fig, Q is a View of a cross section on theline Q-Q of Fig. l. Fig. 3 is a plan of the water receptacle or pan, thecover being removed. Fig. -t is a plan view ot' the cover.

Referring to the drawings l() indicates the receptacle or pan in whichthe water is heated, comprising a casting or a stamping preterabl)T ot'brass composition, rectangular in shape and of an \v desired depth.'l`he interior of the pan is provided with the diagonal delectingribsl1, which extend alternatcly from the opposite sides of the pan toterminate adjacent the other side, the space between the end of the riband the side ot the pan beingsubstantially equal to the space betweenany two adjacent ribs. These ribs divide the interior of the pan toprovide a continuons water channel which begins at one corner of the panand terminates atthe other diagonal corner7 the diagonal arrangement ofthe ribs providing a channel of greater length relative to the area ofthe pan than it' the ribs were arranged to extend inwardl)v at a rightangle to the sides of the pan. It is also to be noted that the diagonalarrangement of the ribs provides for the graduated and progressiveheating of the water, as the cold water entering at the corner (t passesbetween ribs of increasing length and of corresponding intensity ofheat; also that any change in the temperature of the entering water,such as increased coldness which would produce contraction of the parts,exerts its effectupon the shortest' ribs which are most capable toadjust themselves to such contraction without fracture. A cover l2 isprovided for the an and is arranged to be secured thereto lby screwsentering the sides y of the pan, and if desired certain of the ribs maybe arranged also to receive screws to secure the central portion of thecover. A pad 13 of asbestos packing is preferably em ploycd beneath thecover to ilirovide a tighter joint between the cover and the sides ot'the pan and the upper portions or edges ot` the ribs. The pipeconnections 14 and 15' affording the cold water inlet and the hot wateroutlet are tapped into the proper diagonal corners of the cover. Byconnecting the inlet and outlet pipes with the cover i any desired sizeof connection may be employed irrespective of the depth of the pan. Y

lo is a casing and support for the pan otmetal preferably lined withasbestos` mill board not shown in the drawings andv provided with heatescape openings 1T in its top, the pan being supported in the casing bybolts lb`.

.\s a means` for heating the pan l provide the burners li) which areperforated tubes ,supported in the casing beneath the pan and suppliedfrom the nozzles Q0 with any desired combustible. The heat from theseburners is applied beneath the pan and the heated gases ascend aroundthe sides and over the top of the pan to escape from the draft openings1T. Y

The heater may be used in an)Y system or arrangement for supplying hotwater, and several heater units may be inter-connected to secure agreater capacity or intensity. of hot water supply.

Having thus described my invention, I claim u l. A water heatercomprising a rectangular pan having diagonal ribs extending alternatelyfrom opposite sides to provide a c011- tinuous winding channel extendingfrom one corner ot' the pan to the opposite diagonal corner, said ribsbeing of a minimum length at the beginning ot the chalmel thencevincreasing gradually toa maximum in the cen tral portion and thencedecreasing again to a minimum at the termination. and a cover for saidpan provided with inlet and outlet connections leading to and from theabove mentioned channel.

2. A water heater comprising a rectangular pan having diagonal ribsextending alternatel)y from the sides, the ribs decreasingin length atopposite corners and each .rib terminating short ot the opposite side toleave a space of .substantially equal area toV the space iwtween theribs thereby providing a Tn testimony whereof l nffx my Signature 1npx'eence of two Wltnesscs.
